RMX/SO
BASIC-SO
F-2
With RMX/SO BASIC-SO, you can create BASIC programs and program them
into PROMs for permanent reference.
You can configure RMX/SO to execute a PROM-resident
BASIC-SO
program
immediately
on
restart.
If
you wish to interrupt program execution when
BASIC-SO
expects input from
the console, you must enter CONTROL-C followed by a carriage return.
If
you
wish to interrupt a program that has been stopped by a CONTROL-S, type
CONTROL-C followed by CONTROL-Q.
RMX/SO BASIC-SO does not have the EDIT Mode features supported by
ISIS-II BASIC-80.
RMX/SO
BASIC-SO
supports only the console and disk files.
You should also be aware
of
two similarities between RMX/SO
BASIC-SO
and
ISIS-II BASIC-SO:
The
data
formats
and
protocols
of
the ISIS-II
and
RMX·/SO
disk file systems
(DFS) are identical. You can create
data
or program files on one system and use
them
on
the other.
If
you use a random file
or
open a file for output
on
one disk, and then remove
that
disk and insert another, you may destroy files on the new disk. You can
open files for input without problems.
Initializing the Predefined RMX/SO BASIC-SO Configuration
RMX/SO allows many different configurations
of
its modules. Intel supplies two
PROMs that you can use to load BASIC-SO from disk and to execute it.
If
you have
the required hardware, as listed below, you can quickly run the predefined
RMX/SO
BAS I
C-SO
configuration.
An
iSBC 80/30 Single Board Computer
An additional32K bytes
of
RAM
on
two iSBC 016s, or one iSBC 032 board.
An
iSBC
204
Disk Controller.
An
MDS-2DS Disk Drive attached through the cable supplied with the
BASIC-SO package.
An
RS-232C compatible terminal.
An iSBC chassis
and
power supply
If
you have the required hardware, it must be configured as shown below. Refer to
the RMX/SO Installation Guide if you must alter your present configuration. Table
F-l
shows the jumper configurations described in the following paragraphs.
1.
The iSBC SO/30
board
must be wired to conform to the RMX/SO terminal
handler interrupt structure. This requires the wiring changes listed in Table
F-l.
Check your iSBC SO/30 board to verify that these changes have been made. For
further information, refer to the RMX/SO User's Guide.
2. The iSBC on-board PROMs must be addressed at locations
OOOO-OFFF.
This
is
the factory-wired default configuration. These default jumper settings are
shown in Table
F-l.
For
further information, refer to the iSBC

SO/30

Single

Board Computer Hardware Reference Manual, chapter 2.

3.
The iSBC SO/30 on-board RAM must be addressed at locations 4000H-7FFFH.
This
is
the factory-wired default configuration. These default jumper settings
are shown in Table
F-l.
Jumper IS0-171
is
a factory-wired default configuration
that disables off-board access
of
on-board RAM.
For
further information, refer
to the iSBC 80/30 Single Board Computer Hardware Reference Manual,
chapter 2.
